This application claims priority to U.S. Provisional Patent Application Ser. No. 62/693,104 filed Jul. 2, 2018, entitled Industrial Plumbing Fixture Adaptor, the disclosure of which is incorporated herein by reference in its entirety.
The present invention relates to the general art of hand tools, and to the particular field of plumbing tools and methods for using the plumbing tools.
Tub and/or shower faucets are typically mounted through a wall surrounding the tub or the shower stall. The faucets are anchored against rear studs and/or to the wall board, and are linked to the water supply from behind the wall via a water valve stem that projects forward adjacent a wall opening to provide control over the water valve from the room side of the wall.
Most of these water valves are mixing valves which accept both hot and cold water; which control the proportioning and volume of water there through; and which deliver a mixed outlet stream to a tub filler or a shower head when the water valve is turned on. An example of such a mixing valve is disclosed in U.S. Pat. No. 5,467,799 issued to Dana F. Buccicone, et al. on Nov. 21, 1995 and entitled “Mixing Valve”. Other such valves simply control the volume of a single supply of cold or hot water.
Such valves are typically designed such that a valve stem protrudes into the room through a hole in the room wall and a surrounding decorative escutcheon is used to effectively hide the hole in the room wall. The escutcheon also prevents leakage through the wall hole and restricts heat and cold transfer between opposite sides of the wall.
Since the thickness of the wall may vary depending on the construction material selected by the builder or the customer, the plumber or plumbing installer often makes a rough-in installation, and then corrects for the final materials. The final adjustment is often achieved by providing threads on the valve housing which the escutcheon can be tighten down on, thus providing some range of adjustment.
In instances where the wall is particularly thin or unusually thick the amount of adjustment allowed by such threads may be insufficient, thereby requiring the plumber to reposition the valve at a time when access to the valve may be restricted. This type of situation may be time consuming and may damage any construction that has already been made around the valve housing.
Several mounting assemblies have been developed in an attempt to address this problem. For example, U.S. Pat. No. 4,662,389 issued to Muhammad Ighal on May 5, 1987 entitled “Adjustable Stem Assembly” discloses a valve assembly having a valve extension which can be threaded to vary the position of the escutcheon. This mounting assembly has the disadvantage of requiring many components and separate fasteners.
U.S. Pat. No. 4,842,009 issued to Richard L. Reback on Jun. 27, 1989 entitled “Valve Handle Adaptor Kit” discloses a mounting assembly which is suitable for receiving a variety of adaptors. The length of the mounting assembly can be varied by eliminating or adding extension pieces. This mounting system requires multiple parts.
U.S. Pat. No. 4,445,529 issued to Carmen J. Lagarelli on May 1, 1984 entitled “Adjustable Valve Handle” provides a less complex assembly in which a plastic insert with internal splines is adjustably mounted along the length of a stem by a set screw. However, use of a set screw in this context may be awkward.
There is, therefore, a need in the art to provide an industrial plumbing fixture adaptor kit which permits a plumber or worker to have readily available a wide variety of valves, valve stems, and the like which can be used to install a mounting assembly in walls of various thicknesses.
There is a further need in the art to provide an industrial plumbing fixture adaptor kit and a method of using this industrial plumbing fixture adaptor kit.
The present invention provides such needs. The present invention provides an industrial plumbing fixture adaptor kit which comprises a plurality of interchangeable adaptor elements, each of which is appropriate for a particular mixing valve or valve stem and each of which has a length appropriate for the particular job being performed. The kit includes an adaptor element which will connect a selected adaptor element to a handle via a bushing which will permit the handle to be rotated to operate the valve being connected to the handle.
In the invention, the industrial plumbing fixture adaptor kit for mounting a handle to a water valve, comprises: an adaptor comprising an adaptor body having a first end with external threads and a second end; a conical element fixedly mounted on the adaptor body at a location spaced away from the first end of the adaptor body; a hollow tube fixedly attached to the second end of the adaptor body, the hollow tube being linearly aligned with the adaptor body and having a second end which is spaced away from the first end, the hollow tube being rectangular in cross section and having an opening defined in the second end; a bushing mountable on the adaptor body adjacent to the conical element, the bushing being locatable between the conical element and the external threads of the adaptor, the bushing having external threads; a first isolater washer mountable on the adaptor body adjacent to the bushing and between the bushing and the external threads of the adaptor; a handle having internal threads and adapted to be threadably attached to the external threads of the adaptor; and an interchangeable adaptor element having a portion which is rectangular in cross-section and having a first end structured to be received within the defined opening of the hollow tube and having a head which is structured to be connected to the stem of a plumbing hardware.
The kit further comprises a plurality of interchangeable adaptor elements, each having a different length relative to each other and each interchangeable adaptor element has a head for connection of the adaptor element to the plumbing hardware. The adaptor, the bushing, the first isolater washer and the handle form a handle assembly. A fixture trim has internal threads for engaging with the external threads of the bushing of the formed handled assembly for attaching the handle assembly to the fixture trim and for free rotation of the handle within the fixture trim for opening and closing of the plumbing hardware or water valve.
A vapor barrier gasket may optionally be mounted on the adaptor body against the bushing and a second washer may be mounted on the adaptor body and against the vapor barrier gasket. A set screw located adjacent to the second end of the interchangeable adaptor secures the interchangeable adaptor element to the plumbing hardware. The configuration of the head of each interchangeable adaptor element may differ relative to each other and may correspond to the configuration of the plumbing hardware.
In an embodiment of the invention, the kit includes an industrial style plumbing fixture trim made from malleable iron screw fittings that can adapt to any single handle rough-in valve body and mixing valve. The adaptor kit includes a two-part assembly where one part can be swapped out to adapt to any style stem.
The kit of the invention enables a worker to adapt to any rough-in mixing valve that is covered up inside a finished out wall without any damage to the finished wall.
These and other features and advantages of the invention will be better appreciated and understood when the following description is read in light of the accompanying drawings.
The components in the figures are not necessarily to scale, emphasis instead being placed upon illustrating the principles of the invention. Moreover, in the figures, like referenced numerals designate corresponding parts throughout the different views.
